ToA all whom it may concern:

Be it known that I, zen of the United States, and a resident ofWilmington, in the county of Los Angeles and State of California, haveinvented certain new and useful Improvements in Apparatus for Steamingand Cleaning Grain; and l do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to malte and use thesame.

This invention relates to grain steamers and cleaners, and is especiallyadapted for steaming and cleaning barley preparatory to rolling thesame, the object of the same to be to dampen the barley to soften it sothat when it passes through the roller it is not broken ordisintegrated, but simply mashed or iattened out and the steam heats itsufficiently to cause it to retain a part of the caloric of the steamand which is of such a degree that after the rolling operation iscompleted, it will still be hot enough to cause all the dampuess toevaporate therefrom.

A further object of the invention is to obviate the disadvantagesheretofore encountered in rolling barley or any other grain, and withthis and other objects in view the invention consists o the constructionand arrangement of the several parts which will be more fullyhereinafter described and claimed.

In the drawings: Figure 1 is a perspective view of theimprovedapparatus.Fig. 2 is a central longitudinal same. Fig. 3 is a central transversevertical section. I Figdis a detail perspective view of a pair ofcoacting pans or chutes employed in the apparatus.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

Referring tothe drawings, Figure 1 designatos the outer casing of theapparatus which maybe of any form, or shape, but is preferably'thatshown and constructed of suitable material which may be adapted for thepurose.

The parts of the apparatus are separable so that ingress thereto may behad for the purpose of cleaning the same or for other manipulation andare held together by tie-bars 2,

JAMES E. RILEY, a citi vertical section ot the connected at their endsby tie-bolts 3, the said tie-bars and bolts being arranged at the 'topand bottom of the apparatus.

The parts of the casing are made steam tight and at the upper end saidcasing is provided with a feed-pipe or hopper i, under which is aninclined chute 5,that extends diagonally toward the right side of thecasing from one end of tue opening which is constructed to receive thesaid feed-pipe or hopper, and at the opposite end of the said opening isa swinging door or gate, which is limited in its movement in opening bya stop 7. Alternately arranged on opposite sides of the interior of thecasing and in vertical alignment is a series of flanged pans or chutes8, which are deflected or inclined in straight lines and open attheirlower ends. immediately under each of the pans S is another pan 9,having ahorizontal portion l0 and a lower deected or downwardly inclinedend 11, which is arranged parallel with the lower end of the pan orchute S, above the same, but at a distance therefrom. Each of thedownwardly inclined ends 11 of the pans 9, is slightly ex tendedbeyondthe termination of the lower end of the pan 8 above the same, and by thesaid arrangement of the pans 8 and 9, a steam chamber 12 is formed,which is supplied with steam through ports 13. Between each pan 9 andpan 8, next below the same,but nearer to the pan 9, a port 14X isformed, which communi- Gates with steam escape pipes 1i of any suitableextent, through which the steam is conveyed from the apparatus to anypoint desired. This construction is the same on both sides, but at oneend of the apparatus and at the upper left side a small port 14X is alsoprovided, for a similar purpose.

The lower end of the apparatus has a suitable exit pipe 15, throughwhich the grain passes out after being treated, and at the bottom of theapparatus, adjacent to the pipe 14, inclined guide-plates 16, areprovided, which throw or direct the grain into the said pipe 15.

On one side of the casing is secured a steambox 17, having a suitabletapped opening 1S, by means of which communication with a steam pipeleading from a suitable generating source may be made. Each of the ports13, communicates with the said steam-box 17,

FOO

and by this means the apparatus is supplied with steam equally at allparts.

The barley or other grain to be treated is introduced through the pipeor hopper 4, and striking the chute 5 is thrown upon the adjacent pan 8some distance upwardly on the same, and as the said grain in spreadcondition falls 0E of the end of the said pan, the steam passes ontbeween the lower inclined end ll of the pan 9 and the adjacent part ofthe pan 8, thoroughly integrating the grain, heats and moistens thesame, removes all dust and dirt, and at the same time destroys anyanimal life that may exist therein in the forni of bugs and insects. Thegrain then passes through the iirst pan 8, over to the similar pan 8 onthe opposite side of the apparatus where it undergoes the sametreatment, which operation becomes continuous as the grain is thrownfrom one side to the other and nally passes out through the pipe 15. Thesteam ladened with the impurities taken up from the grain, then passesout through the ports 14X and into the pipes 14 and escapes.

It will be seen that the grain in its passage from one side of theapparatus to the other is turned and becomes thoroughly engaged by thesteam and thereby a thorough operation ensues.

It will be understood that many minor changes in the arrangement andconstruction of the several parts might be adopted so far as they arewithin the scope of the invention Without departure from the nature orspirit of the same.

Having thus described the invention, what is claimed as new is l. In anapparatus for steaming grain the combination of an outer casing having asteam box thereon, oppositely disposed steamescape pipes, and a feedpipe or hopper, an inclined chute under the said feed pipe or hopper andalternately arranged series of inclined pans or chutes having other pansor chutes below the same and forming therewith a steam chamber, the saidsteam chamber having ports, connecting with the said steam box thespaces between the said pans orchntes being supplied with portscommunicating with the steam escape pipes, substantially as described.
